Advertorial for Yesim
Youβve just landed after a 15-hour flight from Sydney. Ahead of you are passport-control lines, an unfamiliar airport, tired children and a late-night transfer with your hotel address buried somewhere in an app. All you want is to call a rideshare, message your family and finally get to a shower.
However, your mobile internet is not working, the airport Wi-Fi is overloaded and turning on roaming feels risky because of possible extra charges. Meanwhile, heading to a local SIM-card kiosk means yet another queue, passport checks, confusing tariffs in small print and trying to decipher confusing fine print after a sleepless night.
It is an all-too-familiar scenario for most international travellers, which is why a growing number of Australians are sorting out their connectivity before they even pack their bags. By using eSIM providers, mobile data can be set up through an app at home and activated the moment the plane wheels touch the tarmac.
The traditional roaming trap
For years, travellers have relied on two main options: turning on international roaming with their home carrier or buying a local physical SIM card upon arrival. Both come with their own drawbacks.
The main issue with traditional roaming is cost. Australiaβs communications regulator (ACMA) has repeatedly warned consumers that international roaming for calls, SMS and data can lead to βbill shockβ, with travellers returning home to unexpectedly high charges.
Buying a local SIM has long been considered a cheaper alternative to roaming, but the amount of admin required at the airport can be off-putting.
In many countries, securing a local SIM requires physical registration, passport checks and sometimes even biometric data. This not only forces tired travellers to wait in long lines but also creates privacy risks regarding how personal data is stored by local vendors.
Say goodbye to airport queues
Switching to a digital SIM, or eSIM, removes this friction entirely. Built directly into most modern smartphones, an eSIM allows you to download and activate cellular profiles digitally.
The technology allows travellers to review country coverage, plan durations and exact costs well before committing. You can tailor your coverage to a specific country or an entire region, making it easy to navigate multi-destination itineraries.
Crucially, your primary Australian SIM card remains completely untouched. While abroad, you can leave it active just for urgent incoming text alerts (like bank verification codes) or disable it entirely. Once you land back in Australia, your phone seamlessly reverts to your home data network.
The Swiss alternative
As the technology matures, global digital carriers are finding ways to make data packages more flexible. Swiss-based provider Yesim, which has been developing eSIM technology for seven years, operates as a global carrier across more than 200 destinations. For those unsure of their data requirements, the Pay & Fly plan features a pay-as-you-go model β a single eSIM for more than 170 countries β ensuring users only pay for the data they actually use.
Working with more than 800 carrier partners globally, the Yesim app automatically connects to the local network with the strongest signal. The company also provides a trial plan, granting 500 megabytes for a nominal price of 60 US cents, allowing travellers to test connection quality before committing.
Pricing continues to be highly competitive. For example, seven days of unlimited data in the US could cost as little as US$28.32 (about $40), representing a significant saving compared to other digital roaming alternatives. The platform also features a multiple eSIM capability, allowing users to share profiles and manage them from a single account.
A new travel essential
For Australian travellers, the question is no longer whether internet access will be available abroad, but rather how much it will cost and how quickly it will connect.
Modern travel has evolved, and it no longer begins at an airport SIM-card kiosk. It begins at home, at the same time travellers check their routes, digital documents and travel insurance. Arranging your mobile data in advance is quickly becoming a standard part of the pre-flight routine β rather than an expensive, stressful afterthought at the baggage carousel.
Yesim offers flexible eSIM data packages, including the Global Package (covering more than 80 countries) and the Global Plus Package (covering more than 140). New users can download the app and save 15 per cent on their first data purchase by using the promo code GETYESIM15. For more information, visit Yesim.app
